Question

3. What is the molarity of a solution containing 5.035 grams of FeCl3 in enough water to make 500 mL of solution?

Answer 1

Explanation:

Molarity is a term used to define the concentration of the solution. It is defined as the amount of moles of solute divided by the liters of solutions. Such as

Molarity = moles of solute / liters of solution

In this case, we need to first find out moles of FeCl3

Moles of = mass / molar mass = 5.035/ 162.2 g/mol = 0.031

Thus, molarity = 0.031/ 0.5 = 0.06 M
